SANTA CLARA -- Day 2 of the 49ers' mandatory minicamp meant another day without tight end Vernon Davis and right guard Alex Boone, who are mired in contract disputes.

Coach Jim Harbaugh reiterated his disappointment in the duo's absence but declined to elaborate on his remark Tuesday, that Davis and Boone weren't following the "49er Way."

"I was disappointed in the decision to not come to the minicamp," Harbaugh said Wednesday. "I didn't call anybody out. Some said I did. I thought that (interpretation) was ridiculous."

Davis and Boone risk getting fined up to $70,000 each if they also miss Thursday's minicamp finale.

Harbaugh wanted to keep the focus on those players at camp than the two who aren't.

"To answer the three, four, five follow-up questions, it gets to be badgering, it gets old," Harbaugh said. "I covered it thoroughly yesterday and I don't feel there's anything more to say about it at this time."
